Electronic & Information-Related Technical Departments

This division is made up of the Electronic Materials Division and the Display and Graphic Materials Division. The division drives growth in advanced materials in the field of Information, Telecommunications and Electronics one of the four major growth fields at Toray and carries out the timely development of materials that meet the performance requirements of customers for use in smartphones, flat panel TVs, automobiles, printed materials, and more.

Electronic Materials Technical Dept.

This department develops the adhesive films FALDA™ for semiconductors and high thermal conductivity applications, as well as technologies for the plastic optical fiber RAYTELA™.

Electronic Coating Materials Technical Dept.

This department is engaged in the development of electro-coatings such as PHOTONEECE™ photosensitive polyimide coating and SEMICOFINE™ polyimide coating for semiconductors.

Applied Paste Technical Dept.

This department develops products for a wide range of applications, such as photosensitive functional materials RAYBRID™, scintillators, and the ceramic products TORAYCERAM™.

LCD Materials Production & Technical Dept.

This department promotes product development with the aim of offering total solutions. It has developed TOPTICAL™, a color filter that is indispensable for the small- and medium-sized color LCD panels used in smartphones and automotive displays, as well as paste materials for color filters, touch panel coatings, clear coatings (NS series, PHOTOCLEAR™), and other materials. It also develops technologies for processing equipment.

Graphic Materials Production Sect.

The Graphic Materials Production Sect. develops printing technologies for diverse lineup of products to meet customer needs, including TORELIEF™, a photosensitive relief printing plate developed based on Toray's wealth of technologies in the fields of polymer chemistry and resins.

Flexible touch sensor panel utilizing RAYBRID™

Flexible touch sensor panel utilizing RAYBRID™

Compared with the existing electrode, this panel has features such as 1) low resistance, 2) excellent visibility, 3) good flexibility, and is focused as an unprecedented flexible electrode.

Light-emitting Materials for Organic EL

Light-emitting Materials for Organic EL

Our electron transport materials and hole transport materials have features such as low power consumption, high luminous efficiency, and long service lives.



A printing plate material which enables offset printing without the use of dampening water. It can easily realize high-quality printing, and thus is extremely effective for improving productivity and reducing cost. It also helps protect the environment because no waste fluid is produced during the printing process.
